Despite earlier reports that suggested that Facebook had somewhat acknowledged a problem identified by Symantec, it seems that Facebook is now denying any leak of member profile data. Jaikumar Vijayan reports:

Facebook today denied that it may have accidentally exposed personal user data to advertisers and other third parties for several years, as claimed this week by two security researchers at Symantec Corp.

The researchers in a blog post Tuesday noted that a Facebook programming error — since fixed — could have allowed advertisers to access member profiles, photographs and chat messages and to post messages and mine personal data from them.
